With BlackBerry DevCon Asia set to get under way soon, RIM has made one of the hottest games on the BlackBerry PlayBook available for free in BlackBerry App World, that game of course is Modern Combat 2: Black Pegasus HD. If you happen to live in Singapore and have a BlackBerry PlayBook you can grab the download right now and get into some heavy gaming -- for everyone else, you're still able to download the game but it'll set you back $6.99 in App World.
